SPECTRASWITCH TM: A Patented Optical Self-Testing Electrical Control System
Innovative Optical Switching Technologies for Passive Fiberoptic Systems

Safer by Design
Spectraswitch™ is inherently safer and cheaper than traditional copper-based switching systems:
The remote switch/sensor is completely passive and operates with zero electrical power. All signaling and feedback travel as light over a single optical fiber — eliminating electrical current in the field wiring.
Spectraswitch is also cheaper and easier — using low-cost optical fiber and simple polymer/plastic composite materials instead of increasingly expensive copper. Installation and maintenance are simplified, with no need for complex electrical grounding or shielding.
Key Safety Advantages:
- Arc-Fault & Ground-Fault Proof — No risk of arcing or ground faults in the transmission path
- Explosion-Proof & Spark-Free — Ideal for hazardous locations (Class I Div 1/2)
- Continuous Self-Testing — Instant detection of fiber damage or switch failure
- EMI Immune & Non-Magnetic — Safe for aerospace, defense, MRI rooms, and sensitive environments
By removing electricity from the remote end, Spectraswitch™ dramatically reduces common causes of fires, explosions, and electrical failures while providing reliable, mission-critical performance.

World's First Self-Testing Fiber-Optic Switch/Sensor System
Spectraswitch™
Spectraswitch™ (U.S. Patent No. 11,493,695) is the world’s first self-testing fiber-optic switch and sensor system. It provides an end-to-end solution for remote electrical switching, replacing copper wiring with a patented component-level approach: a passive, zero-power switch/sensor connected via a single optical fiber to an intelligent optocontrolling transceiver that provides switching electrical output via integrated relay (SSR or mechanical) for direct control, or optional TTL logic for PLC/PC/external control integration. This enables reliable control, real-time monitoring, instant fault detection, and mission-critical performance in aerospace, automotive, robotics, and industrial environments—without the weight, EMI risks, short circuits, or failure modes of traditional copper systems. Powered by proprietary Wavelength Selective Reflective Surfaces (WSRS) and continuous optical feedback, Spectraswitch™ supports multi-position and multi-location switching, is explosion-proof, shock-proof, waterproof, EMI-proof, and fully customizable (including optical MEMS for micro-sizes and infrared options). Proof-of-concept prototypes (2-position, 3-position, 3-way, self-testing) are available for demonstration under a standard NDA.
CABLE: Control Affirmed By Light Energy
Spectraswitch™'s Control-by-Light technology is transforming aeronautical and aerospace innovations, automotive technologies, Industrial and advanced robotics—delivering safer, lighter, EMI-immune systems with zero-power remote operation. Novel use cases based on customer interest are continually being developed.
